CORN-HARVESTEE.

Specification of Letters Patent, Patented Sept, 15, 1914 Applicationfiled November 4, 1912. Serial no. 729,317.

To all whom it may concern Be it known that I, LOUIS LARSEN, a citizenof the United States, residing at Lambertson, in the county of Redwoodand State of Minnesota,have invented certain new and useful Improvementsin Corn-Harvesters; and I do hereby declarethe following to be a full,clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and on the axlesection 2.

use the same.

My inventlon has for its object to provide an extremely simpleand-highly efficient corn harvester, and to such ends, the inventionconsists ofthe novel devices and combina tions' of devices hereinafterdescribed and defined in the claims.

The invention is illustrated in the accomq panying drawings, whereinlike characters j indicate like parts throughout the several views.

Referring to the drawings: Figure lis a' plan view of the improvedharvester; Fig. 2 is a View corresponding-to Fig. 1, on an en largedscale, with some parts broken away, and with some of the'exposed partsshown in horizontal section; Fig. 3 is a rear end elevation of theimproved harvester w th some parts sectioned on the line 19 218 of 2;Fig. l is a viewprincipally n vertical section, takenon the irregularline a? m of Fig. 2; some parts being broken away and some of theexposed parts being shown inv section; Fig. 5 isa vertical section takenon the line 00 00 of Fig. 2;, Fig. 6 is a vertical section taken on theline w a of Fig. 1; and Fig. 7 is a view, principally in verticalsection, taken on the line 00 m of Fig 1.

The numeral 1 indlcates a pair of traction wheels loosely journaled on a-two-partaxle,

connected by an arch structure 5 ofsufiicient height to permit the cornstalks to pass thereunder, without-bending the same. As

7 best shown in Fig. '1, the intermediate or horizontal portion 5? ofthe arch structure 5 extends transversely 'of the axle sections 2' and8, and the legs of the arch structure are indicated by the characters 5and 5. The

3 leg 5 directly overlies the inner end portion of the axle section 3and'connects the rear.

end of the transverse portion 5 with the intermediate portion of theaxle section 3. The leg 5 extends vertically downward from the frontendof the transverse portion 5 g and its lower end is connected to aforwardly and laterally projecting extension 2 dicated by dotted lines.To indicate thepo sitions of the draft animals with respect to the poles6, theiri outlines have been indi-.

cated, in Fig. 1, by meansof dotted lines I).

The draft animals are hitched to thepol e s 6 by meansof apair ofwhifiie trees17, connected flexibly, as by a chain or cable 8.? Theouter end portions ofthe connection 8 run over a pairof guide sheaves 9,loosely journaled, each in ahorizontal outwardly projecting bracketextension 10, secured to the poles 6. [To carry thaintermediateportionof'the connection 8 over the rowgof corn stalksembraced, by the poles 6,an'arched channel barhlllis rigidly secured at its ends to the poles '6,as best shown in Fig." 6. Loosely journaled at the ends and intermediateportion of the arched bar 11 arevth'ree guide sheaves 12, over which theintermedi ate portio'nof' the connection 8' works. At

their'forward ends, the polesGare outwardly.

and rev'ersely curved at 13, for the purpose of gatheringthe corn stalksbetween the poles fi under the advance movement of the :machine. A neckyoke 14-, to. which the draftjanimals are attached, is, rigidly connected tojthe forward ends of the poles .6, just to the rear of theircurved ends 13, and its'intermediate portion is bent upward to form anarch 15'. Obviously, the neck yoke arch15 and the arch bar ,llp'ermitthe machine to be driven .over a row .of' corn stalks without bending orbreaking the same. To the axle section 2 is rigidly secured anoperatorsseat 16.

Located between the draft device and the axle of the machine is a pairof. rearwardly converging gathering plates 17. The front edges of thesegatheringplates 17 arerigail secured to the leg 5 of the arch'structure5 and to a substantially horizontally extended frame 19, constructedfro-m a channel bar secured to the axle section 3. d p i A pairof-upright cooperating snapping rollers and 21 are mounted one oneachside o f th e passage 4, located one in adlowing connections areprovided. The tracvanceof the other, so that the corn stalks, in passingthrough the passageway 4, are bent laterallyasthe same are moved throughthe snapping rollers 20 and 21, as best shown in Fig. 1. The upper endsof both ofthe snapping rollers 20 and 21 are loosely j ournaled inth'eintermediate bar 5 of the arch istruoture 5, and the lower ends of thesnapping rollers 20 and 21 are loosely journaled, one in the axleextension 2 and the other in a forward extension?) of the axle section3. f v

F E'. drivi e 2 1.from one of the traction wheels 1, the fol .tionwheel1, which is journaled on the axle .section'S, is provided with along-inwardly projecting hub. extension 1*, having integrally formedthereon a largebevel .gear 22, that is-mounted. within a gearccasing 23,

secured tothe frame 19. Meshing withthe gear '22'is a bevel pinion 24,slidably-mounta ed on a horizontallyiextended shaft 25, jour- I isrigidly seoured'to a counter shaft'37,

gnaled in a pair of bearings 26, on the frame .19. Thep'inion 24 is heldfor rotation-with the shaft 25 but with 'freedom for sliding .movementthereon by'a keyf27, and is provnvidedewith a flanged collar 28. Forslid-- X v pinion 24' intoand out of engagement with the gear 22,ashipper lever 29 is intermedi ately pivoted .at; 30 to the. frame.;19.One

ing the collar, 28 on the shaft 25, to movethe end of this shipper lever29'extends between the-flanges ofthe collar 28 and its other end isconnected toan operating lever 31 by a link 32; The lever 31 ispivotally secured to a cooperating lock segment 33, secured on the frame19. On theshaft 25, outward of the gearv casing 23, is keyed orotherwise se-, cured a sprocket wheel 34, over which and a relativelysmall sprocket wheel 35 runs a sprocket chain'36.. This sprocket Wheellooselyjournaled in bearings'38, on the in{ termediate portion 5*, ofthe arch structure 5. Also keyed or otherwise secured to the shaft37 isa bevel gear 39, that meshes with a bevel pinion 40, keyed or otherwisesecured the'upper' end of theshaft of the snap-' snapping, rollers '20and ping roller 21. The snapping roller-20 is driven from the snappingroller 21' and in areverse direction therefrom by a pair of'intermeshing spur gears 41, keyed or otherwise secured to the upperends of the shafts of the said two snappingrollers. V Y

"A pair of husking rollers 42 and 43 are arranged to receive the ears ofcorn as the sameare broken from the corn stalks by the snapping rollers20'and 21. These husking rollers 42 and 43 are located. atthe bottom ofthe housing 18, just above the axle section 3, extend transverselyofand: at one side of the snapping rollers 20 and 21 and are journaledfinbearings 44, secured to the ,80 frame 19. The huskingroller-42 isdrivenfromthe shaft 25 by asprocket chain 45., which runs over arelativelylarge sprocket wheel 46 on the shaft 25, and, a. relatively smallsprocket wheel 4' ongthevs'haft of the husking roller 42. For drivingthehuskg ing roller 43 from the husking roller 42-and ina reversedirection thereto, a pair of intermeshing spur gears48 is secured totheshafts of saidrollers; I I By reference to Fig. 4, itwill be noted thatthe husking rollers 42 and '43 are' inclined slightly rearwardly, so "asto deliver .the husked "ears" of com through an opening 49in thehousing18, to the lower end of an; 5 inclined elevator" leg 50. Withinthis .elevator leg 50 is mounted a pair of parallel chains 51, arrangedto run over a pair of sprocket wheels 52,. keyedorotherwise se cured tothe rearwardly projecting end "of the shaft of'the husking roller 43 anda pair of idle sprocket wheels 53,loosely journaled in the upper. end ofthe 'elevator leg 50. Securedtothe chains 51fis amultiplicity of liftingflights54, arranged to carry 05 the earsv of corn upward through theelea vator leg'50, as they aredelivered through the opening 49,anddeliver the same outof the upper end thereofinto a wagon, that isdriven between the'rows of eorn stalks beside the cornharvester. c v
